Like this: @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); if (mImageUri != null) { outState.putString(“cameraImageUri”, mImageUri.toString()); } } @Override protected void onRestoreInstanceState(Bundle … Read more

Nexus 5x reverse landscape sensor fix in a android camera preview app

The 5X camera is not “reverse”; it does report the correct camera orientation in its parameters, so no special workarounds are needed, just make sure you’re setting the display orientation correctly: public static void setCameraDisplayOrientation(Activity activity, int cameraId, android.hardware.Camera camera) { android.hardware.Camera.CameraInfo info = new android.hardware.Camera.CameraInfo(); android.hardware.Camera.getCameraInfo(cameraId, info); int rotation = activity.getWindowManager().getDefaultDisplay() .getRotation(); int degrees … Read more

I solved this but by using a different method. Instead of using a broadcast receiver I set up a fileobserver on separate folders that the camera saved to. It’s not as practical as the other way, but it still works fine. Here’s how I set it up: FileObserver observer = new FileObserver(android.os.Environment.getExternalStorageDirectory().toString() + “/DCIM/100MEDIA”) { … Read more
